The captain of a spaceship orbiting planet X discovers that to remain in orbit at 410 km from the planet’s center, she needs to maintain a speed of 68 m/s What is the mass of planet X? (G = 6.67 × 10-11 N ∙ m2/kg2)

Which of the evolutionary mechanisms below best matches with the following scenario: a breeding pair of Somali thrush fly to Madagascar where there are no thrushes and begin a new population.

What kind of equilibrium does overdominance produce?

The concept of __________ is most likely to maintain deleterious alleles in populations.

Consider a series of island populations each founded by a single pair of individuals that are heterozygous at a particular locus.  If the alleles at this locus are neutral, and there is no mutation or migration, describe what the variation will look like after many generations within each population and between populations.  Why do you think it will look like this?

The point at which the rate that a deleterious allele is being eliminated from a population by natural selection is in equilibrium with the rate at which the deleterious allele is being replaced by a new mutation is termed __________.

Ideal random mating populations do not always lose genetic variation via drift at the same rate as observed in an actual population due to a phenomenon called __________.  In these situations, the rate of loss of genetic variation may be higher than expected because some matings fail, some individuals did not mate, etc.

The survival and fertility rates of the offspring of related individuals to be commonly reduced is known as __________.

Which of the evolutionary mechanisms below best matches with the following scenario: a tsunami wipes out most of the hornbills on the Island of Rabaul, Papau New Guinea, leaving a population size of 20.

In terms of the Hardy-Weinberg equilibrium, genetic drift results from a violation of __________ population size.
